FEEDING IVIECHANISM FOR BOARDED FABRICS.

SPECIFICATION forming part of Letters Patent No. 779,712, dated January 10, 1905.

Application filed May 2'7, 1904. Serial No. 210,012.

To @ZZ Lu/1,0my it puny concern:

Be it known that I, CALVIN JACKSON, a citi- Zen of the United States, residing in the city of Berks, State of Pennsylvania, have invented certain new and useful Improvements in Feeding Mechanism for Bearded Fabrics, of which the following is a specification.

My invention relates to apparatus for finishing articles which are mounted upon interior supports during the finishing operation, such as singeing-machines for boarded stockings; and my object is to provide,in connection with the finishing means and means for carrying the boarded articles thereto, means for automatically feeding the boarded articles to the carrying-means from apiled series of boards,as particularly described hereinafter in connecpreferred form of mechanism indicated in the accompanying drawings, the novel features being clearly pointed out in the claims.

Heretofore boarded stockings have been fed to the carrying means by hand, the top board of a pile on either side of the operator being ordinarily lifted and conveyed by him to the carrying means of a double machine. The purpose and effect of my invention is to dispense with this operator and at the same time increase the capacity of thel apparatus and secure greater economy and more satisfactory results in operation.

Figure 1 is a side elevation of a portion of a stocking-singeing apparatus embodying my invention, the singeing means and carrying'- rolls being merely indicated diagrammatically as forming no part of my present invention. Fig. 2 is a forward end elevation showing the driving belt for the carrier-rolls in section on the line 2 2 of Fig. 1. Fig. 3 is an enlarged half-section taken on the line 3 3 of Fig. 1

looking rearward as indicated by the arrow.

The usualsingeing means ofastocking-singeing machine are diagrammatically indicated in Fig. 1 by burners c and ,located, respectively, above and below the line of travel between two pairs of carrier-rolls c CZ and e f of the traveling former-board upon Which the stocking is mounted for finishing treatment on its opposite sides by the gas-jets from the burners.

The boarded stockings are carried to the carrier-rolls c Z in two parallel series,as usual, by a pair of belts 2 2 passing around a forward driving-drum 3 and a rear drum 4, both suitably mounted in the side bars 5 5 of the supporting-frame for `the automatic boardfeeding mechanism shown. This feeding mechanism comprises separate hoppers for holdingthe piled boards from which separate boards are to be fed to the respective carryingbelts 2. Each of these hoppers 6, as shown, is provided with a suitably-inclined sup`porting-wall 7, arranged above the carrying-belt 2 and inclined downward and outward, as shown, to one side of said belt, and with bottom strips 8 8, secured to the hopper ends 9 9. The boards 10 are supported, as indicated in Figs. 2 and 3, in an oblique pile upon these bottom strips 8, with their lower longitudinal edges bearing upon the inclined supportingwall 7, so that a large portion of their weight is directly borne by said inclined wall and only a moderate pressure brought upon the lowermost board by the obliquely-superimposed boards. The lower-most board, as shown, is fed from the pile in the hopper to the carrying-belt 2. To provide forits discharge from the hopper, a sufficient space ll is allowed between the lower edge 12 of the inclined wall and the hopper-bottom 8 8, and to guide the discharged board onto the carrying-belt a slideway extension 13 of said bottom is provided, over the extremity of which the board drops onto the belt.

The means for discharging the separate boards from each hopper comprises, as shown, a pair of hooked devices 15, carried by radius or rock arms 16, preferably fixed to a central longitudinal shaft 17, carrying' similar arms for discharging boards from the twin hopper provided for the second carrying-belt. The free ends of each pair of radius-arms are connected by a longitudinal rod 18 beyond the hopper-bottom, upon which the hooked devices l5 are pivotally mounted at suitable points, as shown, so as to have a limited outward swing thereon against springs 19 sufficient to permit the free upward passage of the device past the lowermost board on its return movement. As indicated in TEig. 3, the hooked devices 15 when moved beyond the lowermost board are sprung into engagement with the outer edge of the latter, the extent of this engaging movement beinglimited, as shown, by a lateral projection 2() on the hooked end of the device arranged to bear against the adjacent bottom strip 8 and its slideway extension during the discharging movement.

rlhe reciprocating movement of the radiusarms is effected, as shown, from a transverse shaft 25, having a crank-disk 26, to which is suitably jointed a crank-rod 27, connected at its upper end to the rod 18, so as to raise and lower the latter, with its connected radiusarms and board-engaging devices, at each revolution of the shaft Q5. This shaft is rotated, shown, by a driving belt or rope 28 from the drum 4.

The length of the hoppers is sufficient to receive the longest boards required; but it is of considerable advantage to use shorter boards when the articles to be treated permit. of so doing, providing they are fed from the hopper with the greater rapidity which such reduced length makes possible without causing one board to contact with a preceding one. therefore provide for varying the frequency of the discharging movements, this being effected, as shown, by merely shifting the driving-belt 28 to one or other of the differentsized pulleys provided on the drum 4L and shaft 25, respectively, thus changing the speed of rotation of the`latter to suit one or other of the two different lengths of board ordinarily employed.

The two pairs of radius-arms 16 provided for the respective hoppers are both fixed, as shown, to the common shaft 17 and are operated in unison by the single crank-rod 27. An

eect of this arrangement 1s to feed a board from each hopper alternately, which is considered preferable. It is obvious, however, that by merely duplicating the crank 26 and crank-rod 27 and allowing the radius-arms to turn upon the shaft 17 instead of being fastened thereto the two pairs of arms may be operated in unison, so as to discharge a board from each hopper at the same time instead of alternately.

The particular mechanism shown and described for carrying my invention into effect may obviously be readily modified withoutdeparting from the spirit of my invention, and 1 do not desire to limit myself to such preferred construction; but
